' INSULATOR PIN.

Specification of Letters Patent.

Patented Dec. 15, 1908.

Application filed. m 4, 1908. Serial No. 480,765.

Be it known that I, CnAnLns G. E'r'rn, a citizen of the United States,residing at St.

Louis, Missouri, have invented a certain new and useful Im r'ovement inInsulator Pins, of which the] ollowing is a full, clear, and exactdescription, such as willen'able others make and use the same, referencebeing had to the accompanying drawings, forming part ofthis-specification, in which Figure 1 is an elevational view showing aninsulator pin constructed in accordance wlth my invention arranged inoperative position on a supportjand Fig, 2' is a pers ctlve'view of thepin with the head remove y 1 This invention relates to insulator pins,

. and articularly to that type of insulator pins position.

who comprise a metal shank provided with a wooden headon which theinsulator is' mounted;

' Themain object of my invention is to rovide an insulator in of thetype referre to Whichcan be PIOdElCGdfl-t a low cost.

Another ob ect of my invention is to provide a metallic insulator pinhavin an integral'portion that is adapted to be ent into engagement withthe support through which the pin extends, thus overcoming the necessity of using a nut tolock the pin in operative Referring'tothe-drawings which illustrate the preferred form of my invention, 1designates'a metallic pin having a screw-threaded portion 2 on WhlCh anon-metalli'ohead 3 is mounted, said head being provided with ex ternalscrew-threads that cooperate withscrew-threads on the interior'of aninsulator, The pin 1 is provided at groove. 5 is formed in the outersurface of the I pm just above thepoint where the tongue 4 is flange.'6. K

' connected to the m, as shown clearly in Fig.-

2. The pin is aso provided with aringshaped flange 6 that prevents waterfrom 7 in which the pin is mounted, and on the underneath side of saidflange are oppositely disposed ribs that sink into the support and thusprevent the in from turning therein. Therlbs 8 preferably merge into theshank of the pin, as shown in Fig. 1, and on the up er side of the flane 6 are tapered ribs 9 that a so merge into t e pin and strengthen the'sufficient diameter to 006 erate with To arrange the pin in operativeositionI first form a hole in the su port and drop' the in into same andthen bend the tongue 4. aterally to engage the underneath side of the Isu'pporh'as shown in Fig. the groove 5 which is ormed in the outer suface of the pin perg I mitting the tongue 4 to bend easily.

skilled in the art to which it appertains to The pin is preferablyformed from malleable ironso that the tonglue 4 will bend readily butifthe tongue shou more nails 10 that are driven into the u per side ofthe sup ort, as shown in dotted lines inF" 1, the ange 6. on the pinbeing provide with notches 11 through which said nails extend. Aninsulator pm of this construction can be produced atalow cost. It islocked in osition by an integral locking de-v vice 4 which cannot workloose. And as the in' is connected to the su port by merely nding .overthe tongue 4 t e pin can .be arranged inoperative osition more quicklythan would be possi le if a nut were em-' 'ployed to connect the pin tothe support.

While I refer to provide'the p n with a ton us 4 t at islocated at oneside of the in do not wish it to be'understood that my broad idea islimited to such a construction for the'tongue 4 could be located at thelongilfn dinal center of the pin without departingroni the spirit of myinvention. I wish it to be understood that my invention is limited to aconstruction com rising a ing materia for, if desired, the pin can beprovided with a screw-threaded portion of the internal threads on theinsu ator. Having thus described my invention, what claim as new anddesire to secure by Letters Patent is: y Y

1. A metallic insulator pin provided .at its lowerfend with an integraltongue that is adapted to be bent into engagement with the support inwhich the pin is mounted; substantially as described.

2. A metallic insulator pin provided at its lower end with an integraltongue that is adapted to be bent into engagement with the support inwhich the pin is mounted, and a groove formed inthe outer surface of thepin adjacent the point where the tongue is connected to the in;substantially as described. 3. A meta ic insulator inprovided at itsupper end with a screw-t eaded portion, a

d'break ofi? the pin 1 can be locked in position by means of one orNeither do "metallic pin rovided witha head 0 insula'tg upper end with ascrew-t non-metallic head mounted on said screw-' non-metallic headmounted on said. screwthreaded portion, and an integral portion at thelower end of said pin which is adapted threaded portion, an integralportion at the lower end of said pin'which is adapted to be bent intoengagement with the support in which the pin is mounted, and aring-shaped flange on said pin which prevents water from running intothe opening in the support in which the pin is mounted; substantially asdescribed. I

5. A metallic insulator pin provided at its upper end with ascrew-threaded portion, a non-metallic head mounted on saidscrewthreaded portion, an integral portion at the lower end of said pinwhich is adapted to be bent into engagement with the support in whichthe pin is mounted, and a ring-shaped flange on said pin which preventswater from runninginto the opening inthe support in which the pin ismounted, said flange being provided with notches that are adapted toreceive fastening devices driven into said support; substantially asdescribed.

6. A metallic insulator pin provided with a ring-shaped flange-forpreventing water from running .into the opening in the su port in whichthe lIl-iS mounted, ribs on t e underneath side 0 saidflange forpreventing the pin from turning, and an integral tongue on the lower endof said pin whichis adapted to be bentinto engagement. with saidsupport, the pin being provided adjacent said tongue with a groove whichpermits said tongue to be bent easily; substantially as described.

In-testimony whereof I hereunto affix my signature in'the presence oftwo witnesses, this twenty-ninth day of April 1908.
